摘要
通过对隐式代数应力模型应力结构的分析，认为湍浮力流动的应力由应变和浮力作用引起，从而利用应力输运的线性近似和平衡近似提出了非线性各向异性湍浮力模型· 该模型避免了数值奇异，其可靠性通过计算和实验的对比得到了验证·
By analyzing the components of Reynolds stresses of implicit algebraic stress model(IASM) in the paper, that Reynolds stresses in buoyant turbulent flows were produced by both strain and buoyancy is considered. Consequently, a nonlinear anisotropy buoyant turbulence model was developed by applying linearity of equilibrium hypothesis to Reynolds stress transports. The model avoids numerical singularity and its reliability is verified by the comparisons between predictions and experimental data.
